Wordpress template

This is for an intranet dashboard and I would like the Front End to be exactly the same as the Wordpress administration area. The backend is based on the Fancy Admin UI which can be downloaded free). Images are provided. The left side is Navigation which should be dynamic and take input from the WP menus. The content area can be populated with widgets from the admin and the layout of the grid should be as follows: 1st row: 3 x 1/3 column 2nd row: 1 x 2/3rd column 1 x 1/3rd column 3rd row: 1 x 3/3rd column 4th row: 3 x 1/3 column 5th row: 1 x 1/3rd column 1 x 2/3rd column Aside from the dashboard We need one page with full page content. We have to be able to use third party applications and shortcodes within those when we populate them in widgets. I dont know how possible it is to make this configurable using WPBakery or some similar front end tool for editing grids and your suggestions are welcome. The theme should be able to be installed as a plugin. We need the menu defined as it is on the picture. The users will go from frontend to backend and they should not be able to see difference when they make the transition. The theme should be able to take the color input based on the values entered in the Settings > General for the Fancy Admin UI. There are only two settings for the primary and secondary color. If this is too difficult it is not mandatory. - We would like to work with the same developer in the future to develop most of the plugins we need for our company intranet so bid fairly because we can have an ongoing project.
